Specification of Letters Patent.

Patented March 3, 1908.

ppheetion filed July 6. 1907. Serial No. 382.486.

To all whom it may concern:

Be it known that I, 'lnoi-(ps G. K-DIDER, citizen of the United States, residing at Mount ()live, in the county of Martin and State of Indiana, have invented certain new and useful Improvements in RatchetlVrenches, ot'nvhich the following is a specification.

This invention relates to improvements in Wrenches of the ratchet type, and has for its object to provide it useful and convenient device of this' character, capable of being used a reversible wrench.

With, this and other objects in viewt e invention consists in certain novel features of construction. and. combination of arts, which will be hereinafter more fully set orth. In the drawings forming a portion of this specification and in which like numerals of reference indicate si'mil'urpurts in the several views :-ligure 1, is an elevation of the wrench partly in section, Pig. 2, aisection on the line 2-2 of Fig. i, l 3, is a section on the line 3-3 of Fig. 1.

Referringnow more particularly to the drawings, there is shown a StOGli 5 terminating at one end in a head 6 end havin its opposite end provided wit-h a. handle 7. lhe head 3 is provided. with upwardly and inwardly projecting lugs S, the purpose of which Wlll hereinafter appear.

ivotelly mounted on the head 6 andlieneef'h the lugs 8 thereon, is n ratchet wheel 9, the pivot pin 10 of which is headed as shown at 1] end is received in a boss 12, formed on the he: d 6, whereby a swivel connection is had. 'lhe wheel 9 is provided with ratchet teeth lb. I

A pawl 15 is pivoted upon the head (i between the nd of the stock 5 and the ratchet wheell). This pawl is substantially crescent shaped, so that itha-s'oppositely disposed teeth 16 nnd l7, ior engagement of the ratchet wheel 9. At the concave-side of the pew it provided with. a centrally located convexity resulting in snglesnt the inner ends of the teeth 16 end 17, Springs 18 and 19 are secured to opposite sides of the stock 5 at the end tlnreof located adjacent to the heed, these s rings having inwardly hcnt free extremities engaging the pawl 15.'

operation As shown in the drawings, the extremities of the springs are arranged 'to'cngage the concave side of the pawl at the end ol'the centrally located convexity thereof, this con- 'vexitv being located at A, as shown. \Vhen the spring 18 thus cngz ges the pawl, the tooth 17 oi the latter is in engagement with the ratchet teeth oi the wheel 9, and when the spring 19 is m engagemcn t with the-concove side of the pnwl the tooth-16 oi' the pawl is in engagement with the ratchet wheel. The of the wrench may thus bev re versed by shifting the position of the pawl, will be readily understood. Springs 18 end 19 are each provided with a serrated finger piece By menns of these finger pieces, the springs may be moved out of engagement with the pawl to permit shifting thereof Formed on the ratchet wheel 9 is ahead 23 and slidable in guides 23 and 24 respectively formed on the wheel, is a second jaw 25, which'is movable toward and :iway from the first namr d jaw, by means of a screw 26 having one end swivelcd in the iixed jaw 33 as shown at 27, and its opposite end is passed through an opening 28' in the movable jaw 25, and is provided with a milled head 29.

F ion] the foregoing description, taken in connection. withthe accompanying drawings, the eonstrtu'tio'n, operation, and advantages of my invention will, be readily understood without requiring an extended explanation. The device is exceedingly uscl'ul for the purpose i'or which it is designed and magv be placed upon the market at a cmnpnratively small cost.

Various changes in the form, proportion, and minor dctails ol" construction may be resorted to without departing from the principle or sacrificing any oi the ndvnnteges of posed terminal ratchet engaging teeth, said opposite ends yieldably in engagement with awl having on its concave side a centrally e ratchet teeth. 10- ocated convexity, and separate springs se- In testimony whereof I afiiX the signature, cured to the end of the stock adjacent to the in presence of two witnesses. ahead, said springs being arranged for inter- THOMAS G.
